第五章 研究結論與建議
第二節 後續研究建議
本節針對本研究結果與研究中所面臨之問題進行探討與建議:
一、研究限制探討
(一)資料揭露齊備性
有鑑於本研究進行時,在選取公司治理衡量變數之資料過程中,往往 面臨資料遺漏或缺失不全之情況,導致能夠進行評等分析樣本數折損甚 多。建議政府主管機關應針對財報相關資料之揭露項目,或相關股權結構
情況明細,進一步確實要求揭露,以確保其財報透明度與公正性。
(二)研究架構層面
本研究進行評等系統架構建立時,面臨相關公司治理評等構面難以實 質量化之困境,如財務報表透明度或企業與利害關係人相關影響等因素,
皆難以由資料庫之數據資料中予以量化衡量,導致公司治理評等系統難以 完全包含各面向因素。
二、後續研究建議
(一)樣本差異分組分析
由於台灣證券市場之有效樣本有限,難以加入許多分組條件進行分組 分析,因此未來研究可考慮選用海外市場進行各種不同分類標準進行分組 分析,例如不同交易市場(上市公司或上櫃公司),或者依照不同產業進行 分組,或待未來台灣證券市場之公司數量增加,可增設入其他分組條件進 一步進行分析。
(二)質性衡量分析
有鑑於本研究所建立之公司治理評等系統全數仰賴量化指標,對於難 以量化之衡量構面便無法進行評估,難免造成公司治理評等系統上之缺失 盲點。因此建議後續研究方向可在時間與成本考量下,納入質性研究之衡 量構面,進一步衡量關於公司治理相關之影響層面,例如財務報表之透明 度、企業社會責任指標等。
